Active clinical trials for "Peripheral Arterial Disease"

Clopidogrel is a prescription medicine used to minimize blood clot formation in patients with cardiovascular disease, particularly those undergoing heart catheterization and stroke. A substantial amount of medical evidence has proven that patients with stroke or heart diseases can benefit from this medicine. However, significant variability in such expected benefits has been found among individuals receiving clopidogrel, with some patients not having the benefit of reduced complications and adverse cardiovascular events. Prior studies have demonstrated a significant association between certain variants on patient's genes (e.g., CYP2C19) and poor response to clopidogrel and, therefore, major adverse cardiovascular events. Variation in other genes and other factors such as platelet activation, weight, diabetes mellitus (a medical condition that produces high blood sugar), concomitant use of other drugs, and smoking status have also been proposed to be related to the same adverse outcomes. In this study, the investigators would like to determine a possible association between these genes and the response to the medication among Caribbean Hispanic cardiovascular patients on clopidogrel. In other populations, it is known that patients with certain genetic variants have lower or magnified responses to this medication when compared to those individuals taking the same dose and not carrying the genetic variations. However, a fundamental gap remains in understanding whether the genomic diversity of Caribbean Hispanics accounts for the observed high inter-individual variability of clinical outcomes to preventive dual antiplatelet therapy (DAPT) with clopidogrel.

Prospective, single-center, single-arm, non-randomized study to assess the safety and efficacy of the FLEX Scoring Catheter in patients with atherosclerotic peripheral artery disease in the superficial femoral and popliteal arteries.

An Early Feasibility Study to Assess Safety and Efficacy of the ChampioNIR® SFA Stent in the Treatment of Patients with Femoro-Popliteal Disease

The PATHFINDER I Registry is a prospective, non-randomized, single arm, multicenter observational study. It is a pilot registry study towards a subsequent large pivotal phase registry. This pilot registry is aimed to evaluate the performance (peri-procedural) and clinical outcomes (intermediate and long-term) of the AURYON™ Atherectomy System, within the initial launch phase of the product in the market.

Despite the best medical management, many patients with peripheral artery disease (PAD) who undergo lower extremity endovascular revascularization experience adverse cardiovascular outcomes and postoperative complications that may increase the risk of acute limb ischemia or amputation. There are no clear molecular associations that could explain the differences in outcomes after endovascular therapy in patients with PAD. The variable outcomes following endovascular therapy may depend, at least in part, on the profile of cytokines involved in inflammatory and atherosclerotic processes. The goal of this observational study is to evaluate the potential use of circulating IL-1, IL-6, TNF-alpha, C reactive protein, HMGB-1, osteoprotegerin, sortilin and omentin-1 levels as biomarkers of major adverse limb events (MALE) and major adverse cardiovascular events (MACE) in diabetic patients with PAD and chronic limb-threatening ischemia (CLTI) requiring a procedure of endovascular revascularization. The main questions it aims to answer are: association between serum levels of IL-1, IL-6, TNF-alpha, C reactive protein, HMGB-1, osteoprotegerin, sortilin and omentin-1 at baseline and major adverse limb events (MALE) after lower extremity revascularization. association between serum levels of IL-1, IL-6, TNF-alpha, C reactive protein, HMGB-1, osteoprotegerin, sortilin and omentin-1 at baseline and major adverse cardiovascular events (MACE) after lower extremity revascularization. Diabetic patients with CLTI requiring lower extremity endovascular revascularization will undergo blood sampling for the dosage of circulating IL-1, IL-6, TNF-alpha, C reactive protein, HMGB-1, osteoprotegerin, sortilin and omentin-1 before the endovascular procedure. Incidence of MALE and MACE will be collected in a 12-months follow-up and will be associated with IL-1, IL-6, TNF-alpha, C reactive protein, HMGB-1, osteoprotegerin, sortilin and omentin-1 serum levels.

The MIMICS-3D-USA Study is a prospective, multicentre, observational study (non-investigational) of the BioMimics 3D Vascular Stent System that evaluates evaluate safety, effectiveness and device performance within a real-world clinical population of patients undergoing femoropopliteal intervention for the treatment of peripheral artery disease.

This is a prospective, randomized, double-blind, double-dummy, and controlled study of DLBS1033 for the improvement of ankle-brachial index in diabetic patients with peripheral arterial disease (PAD). It is hypothesized that the addition of DLBS1033 on top of aspirin treatment will augment significantly the resting ABI in diabetes patient with PAD in comparison with that of aspirin alone.

The investigators are doing this research study to find out if taking Metformin improves walking ability in patients with peripheral arterial disease (PAD). In PAD the arteries (blood vessels) in the legs are narrowed because of the build up of plaque. The leg muscle can hurt in patients with PAD and this is usually described as a cramp or tiredness. This pain is called intermittent claudication. Metformin is an FDA approved medication for the treatment of diabetes. The investigators believe that Metformin may help your leg muscles work better. The investigators will enroll up to 100 subjects in order to find 60 subjects with PAD at Brigham and Women's Hospital (BWH).

This trial will evaluate the safety and efficacy of concentrated bone marrow aspirate (cBMA) to prevent or delay major amputation and/or death in subjects with critical limb ischemia (CLI) due to severe peripheral arterial disease (PAD).

This research study will evaluate the effects of aspirin and dipyridamole alone and in combination on the blood flow in the vessels of the legs. We will examine how these medications are able to inhibit the clotting of platelets in the vessels of patients with PAD, and thereby affect the blood flow in the legs. Platelets are cells in the blood that have the ability to adhere to each other to form clots.
